An updated Segoe UI font is now being tested
The latest Windows 10 preview build introduces an updated Segoe UI font, with Microsoft explaining that it’s supposed to replace the classic Segoe in a way that makes more sense on modern-generation devices. Officially called Segoe UI Variable, the new font is a better choice for devices of all sizes, as it uses an optical axis that allows it to scale to both small and large displays. “Historically, fonts for printing small text were designed differently than fonts designed for large display text. Segoe UI was originally designed to work at 9pt, which makes it a great font for that size, but limits expression at large sizes and lacks legibility at even smaller sizes.
